Chapter 388 Sun Shan was startled and took a step back
This is a teaching area, no entry for outsiders.
Gui Ge'er, Qian Yingyang's servant Qian Wu, and Zhu Pengyun's servant Zhu Si could not keep up. They went to the canteen to get food in dejection for three days. It was almost noon, and the servants had to get the food and go back to the dormitory to wait for their masters to come back and eat.
Master Ma's eyes widened. He looked at Master Yu, then at Sun Shan, and asked again to confirm, "Do you two really want to compete?"
Mr. Ma had just heard from Mr. Yu that in this quarterly exam, one student stood out and scored full marks in the math paper. He is a good candidate for math.
Master Ma was also curious, and after looking at Sun Shan's paper, he quickly said yes.
I felt relieved that Yuelu Academy finally had a student who was interested in mathematics. They had finally found a good candidate.
Why did you turn around and come here to fight?
The situation changed too quickly and Ma Fuzi couldn't accept it for a while.
Master Yu said coldly: "Student Sun thinks his mathematics is invincible, better than mine and you. So he comes to challenge us."
Sun Shan, Qian Yingyang, and Zhu Pengyun opened their eyes wide and looked at Master Yu in surprise.
This is too much exaggeration.
At that moment, Sun Shan and the other two were thinking that Master Yu should not be teaching mathematics, but should be polishing other people's articles. After he polished the article in this way, the original meaning of the article was lost.
Sun Shan quickly denied it three times: "I am not, I didn't, don't talk nonsense."
Master Yu ignored Sun Shan's fierce defense and asked Master Ma to give him some questions quickly, and to ask more in-depth questions that he didn't know how to answer.
If Sun Shan's answer was correct, Yu would admit defeat.
Master Ma is a gentle and peaceful person, unlike Master Yu who is irritable and impulsive.
Master Ma didn't believe what Master Yu had just said.
How could a student dare to challenge the teacher openly?
It must be Master Yu who added some extra details and distorted Sun Shan's words.
If Sun Shan knew what Master Ma was thinking, his eyes would surely light up and he would shout: I am Boya, Master Ma is Ziqi, they are bosom friends.
However, Master Ma also wanted to know how far Sun Shan had learned in mathematics and how good he was.
He nodded and said, "Okay, I'll give you some questions to test you."
So Sun Shan and Master Yu sat obediently at their desks waiting for Master Ma to give them the test questions.
The onlookers Qian Yingyang and Zhu Pengyun squatted in the corner, grinning at Sun Shan and eating melons quietly.
Mr. Ma gave the question quickly.
When Sun Shan took a look, he saw that they were three classic math problems.
The first question is "Chickens and rabbits in the same cage", the second question is "Unknown number of objects", and the third question is "Mouse digging a hole".
These are the classic mathematical problems of "linear equations in two variables", "linear congruence problem" and "encounter problem" respectively.
Mr. Ma asked questions such as "Li Bai gets wine" and "Just in time for pears and fruits", as well as some very common math problems such as plane geometry and four arithmetic operations.
Sun Shan and Master Yu finished it quickly.
For these questions, as long as you understand the meaning of the question and then apply the algorithm, you can naturally give the answer quickly.
Master Ma also asked Sun Shan and Master Yu to write down the solution process in detail.
Finally, Mr. Ma gave a math problem about the application of linear functions in daily life:
In order to sell more chairs, both carpentry shops A and B launched new promotional plans.
Store A only needs to spend 200 taels to purchase the Tianzihao service, and all its chairs will be sold at a 6% discount.
Store B offers a 8% discount on all items.
There is a kind of pear wood chair, and the price marked by both parties A and B is 250 taels.
The college is about to purchase chairs.
(1) The college wants to know how many chairs it would cost to buy them in two stores. How much would it cost to buy them in two stores?
(2) If the academy wants to buy five chairs, which store would be more cost-effective to buy them from?
The questions asked by Master Ma are beyond common sense. Even if there is such an expensive chair, the academy will not buy it.
Sun Shan looked at the question and gave the answer quickly.
After that, Master Ma gave Sun Shan many math problems to solve, and even asked Sun Shan to solve math problems that he himself did not understand.
Sun Shan lived up to everyone's expectations and accomplished it bit by bit.
The area where I was a little hesitant was the reading questions.
Math questions are too short, and just a few words contain many known conditions. If you don’t check the questions carefully, you will miss them.
From noon to afternoon, the onlookers Qian Yingyang and Zhu Pengyun were so hungry that their stomachs growled. Finally, they couldn't stand it anymore and left without saying goodbye.
The two of them are here to eat melons, not to starve to death.
Moreover, when Sun Shan discussed math problems with Master Ma and Master Yu, they were completely confused and their heads were swollen, as if they were listening to a foreign language.
Instead of listening to riddles here, I might as well go back to eat and sleep.
At the beginning, Sun Shan and Master Yu competed in solving problems, but gradually, Master Yu stopped solving problems and instead came over to solve problems with Sun Shan.
Master Yu explained the process of solving the problem to Sun Shan, and then Sun Shan explained his process of solving the problem to Master Yu.
Mr. Ma also joined in to see what differences there were in the three people’s process of solving the questions.
In the end, it turned out that Sun Shan was explaining to Master Ma and Master Yu the questions that they couldn't solve. Sun Shan was more like a master, while Master Ma and Master Yu were more like students.
Sun Shan’s major was not mathematics, but he had a good foundation and understood the theoretical basis. So when he devoted a little attention to mathematics, his dusty memories would fly back and be released slowly bit by bit.
Know more than the native Master Ma and Master Yu.
At this time, Daqian's mathematics had been stagnant and had not made any qualitative leap.
The most important invention in mathematics, calculus, had not yet appeared. The essence of many problems could not be revealed.
When night fell, the three of them saw black everything in front of their eyes. They thought that "the moon was eaten by a heavenly dog" and that something had happened and it had suddenly become dark.
The teaching assistant at the side reminded: "Master Ma, Master Yu, Student Sun, the sun has set and it is dark."
Sun Shan and the other two looked at each other and smiled silently.
Master Yu sighed and said, "Sun Shan, your mathematics is really good, much better than mine. I am ashamed of myself as your teacher."
Ma Fuzi also sighed and said: "The disciple is better than the master. Our mathematics has a successor."
The two teachers sighed and praised Sun Shan.
Sun Shan waved his hands and said modestly, "Master, I am very grateful for your help. My math skills are just average, not as good as you say."
Master Yu stroked his long beard, sighed and said, "It's a pity that mathematics is not valued and not many people study it."
Master Ma disagreed: "Old Yu, it's much better now. The court has included mathematics in the imperial examinations. More and more people will pay attention to it in the future."
Afterwards, Master Ma and Master Yu explained to Sun Shan why mathematics examinations were added to the academy examinations, provincial examinations, and metropolitan examinations in recent years. This was entirely because there was a university scholar who attached great importance to mathematics. Because of his strong recommendation, the court raised the level of mathematics.
Master Ma patted Sun Shan's shoulder and said with emotion: "Sun Shan, our mathematics is valued only because we have people in the court. If we don't have people, how can it be valued? It's a pity that I am old and have always been a Juren. I can never pass the Jinshi exam."
Master Yu also sighed: "Old Ma, I feel the same way. I have taken the exam so many times, but I still cannot pass the exam and become a Jinshi. I cannot serve as an official in the court and promote mathematics like a university scholar. Oh, I am ashamed, ashamed."
Then the two of them looked at Sun Shan at the same time with burning eyes.
Sun Shan was startled and couldn't help but take a step back.
